Either the problem is not Safari-specific, or there are multiple problems with clipping. For your convenience in troubleshooting, I have written this as a defect report. Please fix the product or provide a workaround. Thanks.
Actual Results:
In Safari:
The Safari menu highlights in blue.
The application stops responding for several seconds. (No menus open, etc)

In TextEdit:
Same as Safari
In Firefox 3.x:
